PATHOLOGY

Detailed explanation-1: -Besides this group of neuronal cells, the axons of grey matter are not heavily myelinated, unlike white matter, which contains a high concentration of myelin. [4] The grey matter contains the majority of neuron somas, making it appear tan with circulation but grey when prepared for examination outside of the body.

Detailed explanation-2: -The white matter is composed of bundles of myelinated axons (few cell bodies) that connect various grey matter regions. Myelin is a thin layer, around the axons of white matter neurons and provides the white coloration.

Detailed explanation-3: -Grey matter refers to unmyelinated neurons and other cells of the central nervous system. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord.

Detailed explanation-4: -Consequently, tracts of the central nervous system that contain mostly myelinated nerve fibers and few neurons are referred to as white matter. In contrast, gray matter contains the cell bodies and dendrites of neurons and fewer myelinated nerve fibers.
